TECHNICAL FIELD

The present disclosure relates to a wireless communication system and to a method and apparatus installing a profile for providing a communication service in a terminal. Furthermore, the present disclosure relates to a method and apparatus providing a profile to a terminal in a wireless communication system.

BACKGROUND ART

In order to satisfy a wireless data traffic demand that tends to increase after the 4G communication system commercialization, efforts to develop an improved 5G communication system or pre-5G communication system is being made. For this reason, the 5G communication system or pre-5G communication system is called a beyond 4G Network communication system or a post LTE system. In order to achieve a high data transfer rate, the 5G communication system is considered to be implemented in a very high frequency (mmWave) band (e.g., 60 GHz band). In order to relieve a path loss of a radio wave and increase a transfer distance of the radio wave in the very high frequency band, beamforming, massive MIMO, full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming and large scale antenna technologies are being discussed in the 5G communication system. Furthermore, in order to improve the network of a system, technologies, such as an evolved small cell, an advanced small cell, a cloud radio access network (cloud RAN), an ultra-dense network, device to device communication (D2D), wireless backhaul, a moving network, cooperative communication, coordinated multi-points (CoMP) and interference cancellation, are being developed in the 5G communication system. In addition, in the 5G system, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) that are advanced coding modulation (ACM) schemes, and a filter bank multi-carrier (FBMC), a non-orthogonal multiple access (NOMA) and a sparse code multiple access (SCMA) that are advanced access technologies, and so on are being developed.

Meanwhile, the Internet is evolved from a human-centered connection network through which a human being generates and consumes information to the Internet of Things (IoT) network that transmits/receives information between distributed components such as things and processes the information. The Internet of Everything (IoE) technology in which the big data processing technology, etc. is combined with the IoT technology by connection with a cloud server, etc. has also emerged. In order to implement the IoT, technical elements, such as the sensing technology, wired/wireless communication and network infrastructure, service interface technology and security technology, are required. Accordingly, technologies, such as a sensor network, machine to machine (M2M) and machine type communication (MTC) for a connection between things, are recently researched. In the IoT environment, an intelligent Internet technology (IT) service in which a new value is created for human life by collecting and analyzing data generated from connected things may be provided. The IoT may be applied to fields, such as a smart home, a smart building, a smart city, a smart car or a connected car, a smart grid, health care, smart home appliances, and advanced medical services, through convergence and composition between the existing information technology (IT) and various industries.

Accordingly, various attempts to apply the 5G communication system to the IoT network are being made. For example, 5G communication technologies, such as a sensor network, machine to machine (M2M) and machine type communication (MTC), are implemented by schemes, such as beamforming, MIMO, and an array antenna. The application of a cloud radio access network (cloud RAN) as the aforementioned big data processing technology may be said to be an example of convergence between the 5G technology and the IoT technology.

A mobile communication terminal may access a mobile communication network and is capable of voice communication or data communication service at a determined location or while moving. In this case, in order to provide the mobile communication terminal with the communication service, an appropriate authentication process is necessary. In general, authentication is performed between a mobile communication terminal and the server of a mobile communication company through a universal subscriber identity module (USIM) installed in a universal integrated circuit card (UICC) after the UICC is inserted into the mobile communication terminal. For example, when a customer subscribes to a mobile communication service through a mobile communication company, the mobile communication company provides the customer with a UICC card. When the customer inserts the UICC card into his or her own mobile communication terminal, a proper authentication process is performed along with the server of the mobile communication company in which the same values are stored using an IMSI value and a K value stored in an USIM application installed in the UICC card. Thereafter, the customer can use the mobile communication service. An example of the appropriate authentication process may be authentication and key agreement (AKA) authentication.

A conventional UICC card is fabricated as a dedicated card for a corresponding service provider in response to a request from a specific mobile communication service provider when the card is fabricated. Authentication information (e.g., USIM application and a subscriber identity ID (e.g., may include an international mobile subscription identifier (IMSI)) for network access of a corresponding service provider and an encryption key (e.g., it may be a K value or Ki value) are previously mounted and released. Accordingly, the fabricated UICC card is provided to a corresponding mobile communication service provider and then provided to a subscriber. Thereafter, management, such as the installation, modification and deletion of an application within the UICC, is performed using a technology, such as over the air (OTA), if necessary. The subscriber may use the network and application service of a corresponding mobile communication service provider by inserting the UICC card into the owned mobile communication terminal. If the existing terminal is replaced, the subscriber may use authentication information, a mobile communication telephone number and a personal telephone directory stored in the corresponding UICC card in a new terminal by moving the UICC card from the existing terminal to the new terminal and inserting it into the new terminal.

Meanwhile, unlike in a conventional UICC card fabricated and distributed for a dedicated specific mobile communication service provider, a scheme in which after a customer purchases or obtains a specific UICC card and subscribes to (or purchases) a mobile communication service, when the user subscribes to a specific mobile communication service provider, churns the mobile communication service provider or changes subscription to another service provider, a USIM application, a subscriber identity ID, and encryption key of the mobile communication service provider are remotely installed in the UICC card and such authentication information of various mobile communication service providers can be installed and managed safely and flexibly is sought.

Hereinafter, embodiments of the present disclosure are described in detail with reference to the accompanying drawings.

In this specification, in describing the embodiments, a description of contents that are well known in the art to which the present disclosure pertains and not directly related to the present disclosure is omitted in order to make the gist of the present disclosure clearer.

For the same reason, in the accompanying drawings, some elements are enlarged, omitted, or depicted schematically. Furthermore, the size of each element does not accurately reflect its real size. In the drawings, the same or similar elements are assigned the same reference numerals.

The merits and characteristics of the present disclosure and a method for achieving the merits and characteristics will become more apparent from the embodiments described in detail in conjunction with the accompanying drawings. However, the present disclosure is not limited to the disclosed embodiments, but may be implemented in various different ways. The embodiments are provided to only complete the disclosure of the present disclosure and to allow those skilled in the art to understand the category of the present disclosure. The present disclosure is defined by the category of the claims. The same reference numerals will be used to refer to the same or similar elements throughout the drawings.

In the present disclosure, it will be understood that each block of the flowchart illustrations and combinations of the blocks in the flowchart illustrations can be executed by computer program instructions. These computer program instructions may be mounted on the processor of a general purpose computer, a special purpose computer, or other programmable data processing apparatus, so that the instructions executed by the processor of the computer or other programmable data processing apparatus create means for executing the functions specified in the flowchart block(s).

Furthermore, each block of the flowchart illustrations may represent a portion of a module, a segment, or code, which includes one or more executable instructions for implementing a specified logical function(s). It should also be noted that in some alternative implementations, the functions noted in the blocks may occur out of order. For example, two blocks shown in succession may in fact be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved.

The term “unit”, as used in the present embodiment means software or a hardware component, such as a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC), and the “unit” performs specific tasks. The “unit” may advantageously be configured to reside on an addressable storage medium and configured to operate on one or more processors. Accordingly, the “unit” may include, for example, components, such as software components, object-oriented software components, class components, and task components, processes, functions, attributes, procedures, sub-routines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables. The functionalities provided in the components and “units” may be combined into fewer components and “units” or may be further separated into additional components and “units.” Furthermore, the components and “units” may be implemented to operation on one or more CPUs within a device or a security multimedia card.

In the following description, in describing the present disclosure, a detailed description of a related known function or configuration will be omitted if it is deemed to make the gist of the present disclosure unnecessarily vague. Embodiments of the present disclosure are described in detail with reference to the accompanying drawings.

First, terms used in this specification are described. Terms used in the embodiments of this specification may be defined depending on terms used by a person having ordinary skill in the art, but if a term is related to an embodiment of this specification, the operation or properties of the term may be described depending on a term used in this specification.

Furthermore, in this specification, the UICC covers a UICC functionally similar to the eUICC capable of downloading and installing a profile, but may physically include a UICC detachably mounted on a terminal or embedded in a terminal.

For example, the UICC is a smart card inserted into a mobile communication terminal, and may mean a chip in which personal information, such as network access authentication information, a telephone directory and SMS of a mobile communication subscriber, is stored and which enables safe use of mobile communication by performing subscriber authentication and traffic security key generation when the chip is connected to a mobile communication network, such as GSM, WCDMA or LTE. Communication applications, such as a subscriber identification module (SIM), a universal SIM (USIM), and an IP multimedia SIM (ISIM), are mounted on the UICC depending on the type of mobile communication network accessed by a subscriber. Furthermore, the UICC may provide a security function of a high level for the mounting of various applications, such as an electronic wallet, ticketing, and an electronic password.

For example, an embedded UICC (eUICC), that is, an example of the UICC, is assumed to be a security module of a chip form, which is embedded in a terminal and cannot be detached, but an embodiment of this specification may be identically applied to a UICC which is fabricated in the existing UICC form in such a way as to be detachable and has the same electrical and software characteristics as the eUICC if the UICC has no functional difference from the eUICC.

Furthermore, in this specification, the UICC or the eUICC may be called an electronic device or a small-sized electronic device. An electronic device including the UICC or eUICC may include a control for processing a signal, memory for storing a profile, and an interface unit for access to a terminal if the electronic device is fabricated to be detachable to/from the terminal, although it will be described in the drawing of a corresponding part.

The UICC according to an embodiment of the present invention may download and install a profile using a common IP network, such as a wireless communication network or WiFi. Various embodiments of the present disclosure may be applied regardless of the type of a network over which a profile is downloaded.

In this specification, the profile may mean a profile in which at least one of an application, a file system and authentication key value stored in the UICC has been packaged in a software form.

In this specification, a USIM profile may have the same meaning as a profile or may mean that information included in a USIM application within the profile has been packaged in a software form.

In this specification, a profile server may be expressed as a server, including a subscription manager (SM), subscription manager Plus (SM+), subscription manager data preparation plus (SM-DP+), a profile delivery platform, a profile delivery server, subscription manager data preparation (SM-DP) and subscription manager secure routing plus (SM-SR+). The profile server may be internally implemented as a plurality of physical servers. For example, the profile server may be internally divided into an SM-DP server and an SM-SR+ server and implemented. The profile server may transmit an encrypted profile to a terminal when Credential transmitted by the terminal is successfully verified. The Credential may be Credential for verifying the profile download right of the terminal.

In this specification, a routing server may be a server previously configured in a terminal. The pre-configured server may be configured when the terminal is fabricated or when the initial operation of the terminal starts. Furthermore, when the terminal starts an operation for profile download, the server may be configured. The routing server sets up a routing session and delivers a communication packet for the profile download of the terminal to a profile server. The name of the routing server denoted in this specification is merely an expression that represents the function of the routing server, and it is to be noted that the function may be implemented in any server apparatus having a network function.

In this specification, a mobile communication network, that is, an object over which a message or information is transmitted/received, may be a specific node of a mobile communication network. For example, the mobile communication network may be a base station, subscriber information management node or mobility management node of a mobile communication network.

In this specification, the mobile communication network may include a home location register (HLR) and authentication center (AuC) server which accesses a terminal and performs a subscriber authentication function, and includes a network and server capable of providing voice communication or data communication through access after authentication.

A term “terminal” used in this specification may be denoted as a mobile station MS), a user equipment (UE), a user terminal (UT), a wireless terminal, an access terminal (AT), a terminal, a subscriber unit, a subscriber station (SS), a wireless device, a wireless communication device, a wireless transmit/receive unit (WTRU), a mobile node, a mobile or other terms. In this specification, if a terminal is denoted unless otherwise classified, it may include a thing into which an UICC is inserted in a socket form and which includes even the UICC or may include all of things embedded into the terminal like an eUICC. Furthermore, if a UE is connected with the help of a separate communication device using a technology, such as a Bluetooth SIM access profile between the UE and a UICC, an electronic device including even the corresponding UICC may be called a UE.

Various embodiments of a UE may include a cellular telephone, a smartphone having a wireless communication function, a tablet having a wireless communication function, a wearable device having a wireless communication function, portable digital assistants (PDA) having a wireless communication function, a wireless modem, a portable computer having a wireless communication function, a photographing device, such as a digital camera having a wireless communication function, a gaming device having a wireless communication function, music storage and playback home appliances having a wireless communication function, Internet home appliances capable of wireless Internet access and browsing, and a portable unit or terminals in which combinations of such functions have been integrated. Furthermore, a measuring device having a communication function may also be included in the UE.

Furthermore, in this specification, a UE may include a machine to machine (M2M) terminal or a machine type communication (MTC) terminal/device, but is not limited thereto.

In this specification, a profile identifier may be expressed as a factor matched with profile identification information, a profile ID, an integrated circuit card ID (ICCID) or an issuer security domain-profile (ISD-P). For example, the profile ID may indicate a unique identifier of each profile. The profile identifier may be used to identify a profile in a network.

In this specification, a UICC identifier may be expressed as a unique identifier a UICC for a UE, a UICC identifier or an EID (eUICC ID).

Hereinafter, a UICC which downloads and installs a profile is collectively called an eUICC, for convenience of description.

FIG. 1 is a diagram showing the configuration of a mobile communication system for providing a mobile communication service.

Referring to FIG. 1, the mobile communication system of FIG. 1 may include at least one of a UE 110, a first mobile communication network 120, a second UE 115, a first network 130, and a service provision server 140.

The UE 110 has a first Credential for accessing the first mobile communication network 120. In this case, the Credential may be information stored in a UICC card included in the UE 110 or may be information stored in an embedded secure element (eSE) embedded in the UE. The Credential may refer to an IMSI, K or Ki value or may refer to a calculation value obtained by calculating one or more of an IMSI, K and Ki values.

The first mobile communication network 120 includes a server and mobile communication network themselves which enable a mobile communication network to be used if the Credential stored in the UE 110 is successfully verified. The first mobile communication network 120 may provide a voice call or data communication or both a voice call and data communication to the UE 110. In the case of data communication, data communication to the service provision server 140 outside the mobile communication network through the first network 130 in addition to data communication within the mobile communication network may be provided.

The first network 130 refers to a network connected to the first mobile communication network and also connected to the service provision server 140. The first network 130 may refer to a network to which one or a plurality of networks has been connected.

The service provision server 140 refers to a server providing a data service while operating in conjunction with the UE 110 over the first network. An example of the data service may be an Internet search function.

The second UE 115 is a device accessing the first mobile communication network 120 and capable of a voice call with the UE 110. If the UE 110 is a UE not having a voice call function, the second UE 115 may be omitted from the configuration of the system.

FIG. 2 is a diagram showing a flow of a communication service provided by a mobile communication system.

Referring to FIG. 2, a mobile communication system may include at least one of the UE 110, the first mobile communication network 120, the second UE 115, the first network 130, and the service provision server 140.

At operation 210, the UE 110 may access the first mobile communication network 120 through communication with the first mobile communication network 120. In this case, the UE 110 may send the aforementioned Credential to the first mobile communication network 120. The first mobile communication network 120 may determine whether or not to permit the access of the UE 110 to the first mobile communication network 120 by verifying the received first credential.

If access to the first mobile communication network 120 is permitted, the UE 110 may use a voice call with the second UE 115 over the first mobile communication network 120 (operation 220) or may access the first network 130 over the first mobile communication network 120, may access the service provision server 140 and may be provided with services (operation 230).

The aforementioned mobile communication system has problems in that a UICC card must be replaced in order to access the mobile communication network of another service provider in such a manner that the Credential of a specific mobile communication company is mounted on a UICC or an eSE embedded in a UE and services is provided by accessing the mobile communication network of the corresponding mobile communication company and an eSE chip must be replaced in order to change a service provider in the case of an eSE embedded in a UE.

FIG. 3 is a diagram showing the configuration of a mobile communication system for providing a mobile communication service according to an embodiment of the present disclosure.

Referring to FIG. 3, the mobile communication system may include at least one of a UE 310, a first mobile communication network 320, a first network 325, a second mobile communication network 330, a second network 335, a routing server 340, a profile server 350, a service provision server 360, a third network 345 and a second UE 315.

A communication method of an embodiment of FIG. 3 is a method using a mobile communication network, including the UE 310 having a first Credential, the second mobile communication network 330 determining whether or not to permit access to a mobile communication network using the first Credential, the second network 335 that may be additionally accessed if access to the second mobile communication network is possible, the routing server 340 capable of being accessed over the second network 335 and determining whether or not to permit routing using the second Credential of the UE, the profile server 350 capable of being accessed over the third network 345 that the routing server 340 may access and of being accessed by the routing server 340 over the third network 345 and determining whether or not to provide a profile included in a fourth Credential using the third Credential of the UE 310, the first mobile communication network 320 determining whether or not to permit access to the mobile communication network using the fourth Credential, the service provision server 360 capable of being accessed over the first network 325 that may be additionally accessed if access to the first mobile communication network 320 is possible and the first network 325 that may be accessed over the first mobile communication network 320, and the second UE 315 capable of communication over the first mobile communication network 320.

Referring to FIG. 3, the UE 310 may access the third network 345 through Internet access, such as WiFi or Bluetooth (BT), but if the UE 310 accesses the second mobile communication network 330 only, access to the third network 345 may be limited. A method for the UE 310 to access the routing server 340 may be a method for the UE 310 to use a predetermined Internet protocol (IP) address or a uniform resource locator (URL). For example, the address of the routing server 340 may have been stored in the UE 310. For another example, the address of a server that notifies the UE 310 of the address of the routing server 340 may have been stored in the UE 310.

FIG. 4 is a diagram showing a flow of a communication service provided by a mobile communication system according to an embodiment of the present disclosure.

Referring to FIG. 4, the mobile communication system may include at least one of the UE 310, the first mobile communication network 320, the first network 325, the second mobile communication network 330, the second network 335, the routing server 340, the profile server 350, the service provision server 360, the third network 345, and the second UE 315. The profile server may be plural.

At operation 401, the UE 310 sends a connection request message to the second mobile communication network 330. The connection request message may include a first credential. The first credential may be identification information for accessing the second mobile communication network 330. The first credential may have been stored in the UE 310. For example, the first credential is information stored in the UICC or eSE of the UE 310 and may be information, such as an IMSI, K or Ki, or may be a value dynamically calculated from the information. At operation 403, the second mobile communication network 330 may verify whether the UE 310 has a right to access the second mobile communication network 330. For example, the second mobile communication network may verify a first Credential. The second mobile communication network 330 may verify whether the UE 310 has a right to access the second mobile communication network 330 by verifying the first credential.

At operation 405, the second mobile communication network 330 may transmit a verification response message to the UE 310. If the second mobile communication network 330 fails in the verification of the first Credential received from the UE (if it is determined that the UE does not have an access right to the second mobile communication network), it may reject the connection request of the UE 330.

If the second mobile communication network 330 succeeds in the verification (if it is determined that the UE has an access right to the second mobile communication network) at operation 405, it may permit access to the second mobile communication network 330. In this case, the operation of the UE 310 that has accessed the second mobile communication network 330 may be limited to some Internet access including access to the routing server 340 depending on the configuration of the second mobile communication network 330. For example, the access of the UE 310 to the second mobile communication network 330 may be limited to an operation for profile reception through a domain name server (DNS) and the routing server 340.

When the UE 310 is successful in the access to the second mobile communication network 330, it accesses the second network 335 over the second mobile communication network 330 and accesses the routing server 340. The second network 335 is a network that connects the second mobile communication network 330 and the routing server 340, and may be connected by one or a plurality of networks. Furthermore, the second network 335 may be a network over which the first network 325 and the third network 345 are connected or not connected.

At operation 407, the UE 310 may transmit profile download-related information to the routing server 340. The UE 310 may transmit the profile download-related information to the routing server 340 over the second network 330. For example, the profile download-related information may include a profile server identifier. The profile server identifier may include identification information of a profile server, for downloading a profile requested by the UE 310. Furthermore, the profile download-related information may include information capable of determining whether the UE 310 has a routing request right to download the profile from the profile server 350 through the routing server 340. For example, the profile download-related information may include a second Credential. In this case, the second Credential may include a certificate, signature, etc. The profile download-related information may include a profile server identifier. Furthermore, the profile server identifier may be an SRID, DPID or SMID, and the identifier may be mapped to the Internet address of the profile server 350.

At operation 409, the routing server 340 may verify the routing request right of the UE 310. The routing server 340 may verify the routing request right of the UE 310 based on the profile download-related information. The routing server may verify the routing request right by verifying the second Credential. The routing request right may be information indicating whether the UE 310 has a profile download right via the routing server 340.

At operation 411, the routing server 340 may deliver a result of the verification to the UE 310. If the verification fails, the routing server 340 delivers a verification failure indication message (e.g., Reject message) to the UE 310. If the verification is successful, the routing server 340 delivers a verification success indication message (e.g., success message) to the UE 310. The routing server 34 may start a routing session if the verification is successful.

At operation 413, the UE 310 may transmit a profile download request message to the routing server 340. For example, the UE 310 may transmit the profile download request message to the IP address of the routing server 340. In the embodiment of FIG. 4, the UE 310 transmits the profile download request message to the routing server 340 not the profile server 350. The profile download request message may include data for the profile download. The data for profile download may include profile download identification information. The profile download identification information may include information identifying whether the UE 310 has a profile download right. The profile download identification information may include a third credential. The third Credential may include a certificate, signature, a one-time public key or an EID corresponding to the UE 310. The certificate may be an elliptic curved digital signature algorithm (ECDSA) certificate corresponding to an eUICC. The signature is a personal key corresponding to a public key included in the ECDSA certificate and may be a signed value. The disposable public key may be an ephemeral public key. The certificate, signature, disposable public key and EID may be transferred through the same message or may be transferred through separate messages.

At operation 415, when a routing session stars, the routing server 340 may deliver the profile download request message to the profile server 350. The routing server 340 may deliver the profile download request message to the profile server 350 corresponding to a profile server identifier received from the UE. In this case, the routing server 340 may deliver the profile download request message through the profile server 350 and the third network 345. The routing server 340 may deliver the profile download request message, received from the UE and including profile download identification information (e.g., the third credential), to the profile server 350.

At operation 417, when the profile download request message is received, the profile server 350 may verify whether the UE 310 has a profile download right. The profile server 350 may verify whether the UE has a profile download right using the profile download identification information (e.g., the third credential).

If the verification of the right fails as a result of the verification of the profile download identification information, at operation 419, the profile server 350 may deliver a profile download Reject message to the UE 310 via the routing server 340. At operation 420, the routing server 340 may deliver the profile download Reject message, received from the profile server 350, to the UE 310.

If the verification is successful, at operation 423, the profile server sends the profile to the UE 310 via the routing server 330. The profile server 350 may encrypt a profile including first mobile communication network access right information (e.g., a fourth credential) at operation 421. At operation 423, the profile server 350 may transmit the encrypted profile to the UE 310 via the routing server 330. The profile may refer to a profile package.

At operation 424, the routing server 340 may deliver the profile, received from the profile server 350, to the UE 310.

At operation 425, the UE 310 may install the downloaded profile. The UE 310 may install the profile in a UICC.

At operation 427, the UE 310 sends a connection request message to the first mobile communication network 320. The UE 310 sends the connection request to the first mobile communication network using the fourth Credential of the profile included in the downloaded profile.

At operation 429, the first mobile communication network 320 verifies the first mobile communication network access right of the UE 310. For example, the first mobile communication network 320 may verify the access right of the UE 310 to the first mobile communication network by verifying the fourth Credential.

If the verification fails, at operation 431, the first mobile communication network 320 may transmit a Reject message to the UE 310. If the verification is successful, at operation 433, the first mobile communication network 320 may transmit a connection success message to the UE 310.

If a connection with the first mobile communication network 320 is successful, the UE 310 may perform a voice call with the second UE 315 over the first mobile communication network 320 at operation 435, and may access the first Internet over the first mobile communication network 320, may access the service provision server 360, and may be provided with services at operation 437.

Through the above method, the UE 310 may download the profile for using the first mobile communication network 320 using the routing server 340. In order to download the profile download the profile including fourth Credential information for accessing the first mobile communication network 320, the UE 310 accesses the second mobile communication network 330 using the first Credential that provides limited access to the second mobile communication network 330. The UE may download a profile including the fourth Credential information from the profile server via the routing server 340 that may be accessed through the limited access after accessing the second mobile communication network 330. In this case, the routing server 340 may use the second Credential in order to limit a data routing function for a specific UE request.

FIG. 5 is a diagram showing a flow of a communication service provided by a mobile communication system according to another embodiment of the present disclosure.

Referring to FIG. 5, the mobile communication system

the mobile communication system may include at least one of the UE 310, the first mobile communication network 320, the first mobile communication network 325, the second mobile communication network 330, the second mobile communication network 335, the routing server 340, the profile server 350, the service provision server 360, the third network 345, and the second UE 315. The profile server may be plural.

At operation 501, the UE 310 sends a connection request message to the second mobile communication network 330. The connection request message may include a first credential. The first credential may be identification information for accessing the second mobile communication network 330. The first credential may have been stored in the UE 310. The first Credential is information stored in the UICC card within the UE 310 or the eSE within the UE 310 in order to access the second mobile communication network 330, and may be information, such as an IMSI, K or Ki, and a value dynamically calculated from the information.

At operation 503, the second mobile communication network 330 may verify whether the UE 310 has a right to access the second mobile communication network 330. For example, the second mobile communication network may verify the first Credential.

At operation 505, the second mobile communication network 330 may transmit a verification response message to the UE 310. If the second mobile communication network 330 fails in the verification of the first Credential received from the UE (if it is determined that the UE does not have an access right to the second mobile communication network), it may reject the connection request of the UE 330 (Reject transfer).

If the second mobile communication network 330 is successful in the verification (if it is determined that the UE has an access right to the second mobile communication network) at operation 505, it may permit access to the second mobile communication network 330 (success transfer). In this case, the operation of the UE 310 that has accessed the second mobile communication network 330 may be limited to some Internet access including access to the routing server 340 depending on the configuration of the second mobile communication network 330. For example, the access of the UE 310 to the second mobile communication network 330 may be limited to an operation for profile reception through the routing server 340.

When the UE 310 is successful in access to the second mobile communication network 330, at operation 506, the UE accesses the second network 335 over the second mobile communication network 330 and accesses the routing server 340. The second network 335 is a network that connects the second mobile communication network 330 and the routing server 340 and may be connected over one network or a plurality of networks. Furthermore, the second network 335 may be a network connected to or not connected to the first network 325 and the third network 345.

The UE 310 may transfer discount coupon information when it is connected to the routing server 340. The discount coupon information may be included in a web URL address and transferred.

At operation 506, an operation corresponding to 407 to 411 of FIG. 4 may be performed.
